i have been solving this problem for weeks, hope someone can help me out, this is what i get for my zencart domain header under test

HTTP Status Code: HTTP/1.1 302 Moved Temporarily
Date: Wed, 07 Oct 2009 03:35:15 GMT
Server: Apache
Cache-control: private
Set-Cookie: cookie_test=please_accept_for_session; expires=Fri, 06-Nov-2009 03:35:15 GMT; path=/; domain=www.mysite.com
Location: http://www.mysite.com/index.php?zenid=
Connection: close

something wrong here? as a 302 seems not good for googlebot to index,

and when i use xenu software to check i got the following result

List of redirected URLs
